[GoogleCodeExporter]

What steps will reproduce the problem?

What is the expected output? What do you see instead?

• Merged into: #116

[GoogleCodeExporter]

this plugin needs python 2.7.  this should be fixed.

This is a duplicate of issue 116. It has been already fixed in the repository:

48,49c48,50
<         mods = { m.i_modulename : [p, m.search_one("namespace").arg]
<                  for m,p in unique_prefixes(ctx).items() }
---
>         mods = {}
>         for m,p in unique_prefixes(ctx).items():
>             mods[m.i_modulename] = [p, m.search_one("namespace").arg]

Otherwise, version 1.5 works with Python 2.7.
